I have an old project that was written in Laravel 5.3 , I recently rewrote all the code using the 5.5
My question is how to organize this in Github, currently the master branch supports my project based on Laravel 5.3, locally I have the project rewritten in version 5.5
As a solution, I thought about migrating version 5.3 to another branch and uploading 5.5 to the master, but I do not know if that's how it works. If this is the path, how can I perform these steps?
